Two stable isotopes of lithium and have respective abundances of 7.5% and 92.5%. These isotopes have masses 6.01512 u and 7.01600 u, respectively. Find the atomic mass of lithium. Ans)(6.01512*7.5/100)+(7.01600*92.5/100)=6.940934
What is the means in which light waves travel? Ans: Light is the only type of wave that doesn't require a medium. Confirmation that light will travel through vacuum is the
